If homomorphic encryption is too good, why does the cloud still use AES or Blowfish encryption techniques?

Thanks. We'll let you know when a new response is added.

AES encryption solution is transparent to the
application and can be combined fast and simply without any changes to
application. The key is never kept next to the encrypted data, since it may cooperation
the key also. To store the keys, a physical key management server can be
installed in the user’s sites

    First, there is no such thing as "the cloud". Asking "why does 'the cloud'..." do something is meaningless. Second, AES/Blowfish are widely recognized as fully viable for the foreseeable future for data encryption. There is no reason at this time to spend time/money for the effort to switch to anything else.

    The better question would then be "Why spend to do anything else when AES/Blowfish are more than sufficient?"

    I agree with Raven, if AES/Blowfish are widely acceptable and have proven to be sufficient, why look elsewhere? I guess it comes down to your companies needs. It may be that these methods are not sufficient for legal means.

    They widely use AES, while it has 128 bit block size rather use blowfish. Blowfish has 64 bit block size. Still now there is no alternative instead of these two security level. They are chip also and well known experts can be found. It also helps fast software configuration and have small memory footprint.
